POSITIVE SHUTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 373,423, dated November15, 1887.

Application filed November 11, 1886. Serial No. 218,624. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK K. WRIGHT, of the city of Rochester, inthe county of Monroe and State of New York, have invented new and usefulImprovements in Positive Shuttle-Motions for Looms, of which thefollowing is a specification.

This invention relates to that class of shuttle-motions in which theshuttle is operated positively by two carriers arranged on oppositesides of the loom and receiving and delivering the shuttle from one tothe other within the warp-shed by means of an automatic lookingmechanism.

The object of my invention is the production of a simple and efficientlocking mechanism, whereby the shuttle is automatically attached to anddetached from the carriers.

My invention consists of the improvements which will be hereinafterfully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section of myimproved shuttle and the inner ends of the carriers. Fig. 2 is a topplan view of the same parts, one ofthe carriers being shown in ahorizontal section taken in line a: a', Fig. 1. Fig. 3 is a horizontalsection th rough the socket of one of the carriers. Fig. 4 is a sideelevation of the end of one of the carriers. Figs. 5, 6, and 7 arecross-sections in lines 11 1 to w, and z z, Fig. 1, respectively. Fig. 8is a plan view of the l0cking-bar of the bobbin-arbor. Fig. 9 is aperspective view of one of the catches which are attached to thecarriers. Fig. 10 is a detached plan view of the locking-lever.

Like letters of reference refer to like parts in the several figures.

A represents the shuttle-body provided with pointed arms a (0, having acentral cavity, a for the reception of the weft-bobbin.

B is the arbor for the bobbin, secured to the shuttle body A by abifurcated locking-bar, b, in the usual manner.

0 represents a locking-lever pivoted to the shnttle-body and having itsarms 0 0 arranged in grooves 62 d, formed in the upper sides of the armsa a of the shuttle-body. The lever Cis pivoted upon the upper end of thearbor B, and is curved to lie closely against the upper side of theshuttle-body, as represented in Fig. 1.

E E represent locking-heads, formed on the ends of the lever-arms c cand projecting upwardly therefrom. Each of the heads E E is providedwith an oblique face, e, and an abrupt shoulder c.

ff represent pins extending transversely through the grooves d d in theshuttle-arms a a, and arranged closely against the upper sides of thelever-arms c 0, so as to confine the latter in the grooves and preventthe lever from becoming detached from the shuttle.

G G represent the shuttle-carriers arranged horizontally on oppositesides of the loom and moving simultaneously inwardly and out wardly in awell-known manner. Theshuttlecarriers may be operated by any suitablemechanisn1for instance, that described and shown in Letters Patent No.299,610, granted to me June 3, 1884. The carriers are provided in theirinner ends with sockets g g, respectively, for the reception of theshuttle-arms a a.

H H represent movable catches arranged obliquely in the upper portionsof the sockets g g at the proper height to engage against thelocking-heads E E of the lever C. Each of these catches consists of awedge shaped bar, 1', a disk, 6, and a pivot, i. The bars i are arrangedobliquely and with their narrow ends inwardly or toward the shuttle. Thedisks z" are arranged on the upper sides of the bars 2', and are seatedin bearing-pieces J J, secured to the upper sides of the carriers. Eachbearing-piece is provided on its under side with a recess, j, in whichthe disk 71 is seated.

The carriers G G are square in cross-section, and are provided in theirupper sides with elongated openings 7c, in which the barsiplay, asrepresented in Figs. 2, 3, and 6. These openings are wide enough topermit of the requisite movement of the bars 2', but are narrower thanthe disks i, so that by inserting.

the bar 2' in the opening is, with the disk 1'' resting on the top ofthe carrier over the opening 70, then placing the bearing-piece J on thepivot i and securing the bearing-piece to the'carllel'illlll by rivetingor otherwise, the catch is attached to the carrier-arm in a simple andinexpensive manner. Each of the catchesH H is held in its normalposition by a spring, Z, secured with its rear portion to the carrierand bearing with its front end against the catchbar i, in such manner asto hold the bars obliquely and parallel, or nearly so, with the obliquefaces 6 of the locking-heads E E.

m represents outwardly curved or diverging wings secured to the innerends of the carriers for guiding the shuttle arms into the sockets ofthe same.

In the position of the parts represented in Figs. 1 and 2 the shuttle isattached to the carrier G and detached from the carrier G. The

bar t of the catch H, which is attached to the carrier G, is engagedbehind the locking-head Eof the lever O, and the innerend of the carrierrests againstthe shoulder a at the junction of the shuttle-arm a withthe body of the shuttle. A similar shoulder, a, is formed at thejunction ofthe arm a with the'shuttle-body.

When the carrier G moves toward the shuttle in the direction of thearrow in Fig. 1, the shuttle-arm a enters the socket g of the carrier G,and the oblique bar 43 of the catch H strikes against the oblique face 6of the locking-head E. The front end of the bar i is held againstoutward movement by resting against .the adjacent side of the slot7c,-and the bar 11 therefore moves the head E laterally in the directionof the arrow in Fig. 2, swinging the lever O on its pivot. When thepivot .of the catch H in its movement toward the shuttle has passed thehead E, the bar z'yields laterally by turning on its pivot anddeflecting the spring Z until the rear end of the bar '5 has cleared theabrupt shoulder e of the head 'E, when the spring returns the catch H toits normal position. The rear end of the bar 2' now rests against theshoulder e of the head E, and the inner end of the carrier G restsagainst the shoulder at of the shuttle, thereby attaching the latterfirmly to the carrier G,aud compelling it to move with the carrier.

The above-described lateral. movement of the lever C swings thelocking'head E at the other end of the shuttle away from the bar 2' ofthe catch H, and permits this bar 6 to move past the head E as thecarrier G moves away from the shuttle. \Vhen the pivot of the catch Hhas passed the head E during the outward movement of the carrier G, thebar 2' of the catch H yields by turning on its pivot and deflecting thespring 1 until the bar t clears the head E,

position by the spring Z. When theearrier G moves toward the shuttle, itis interlocked with the shuttle and the carrier G is detached therefromin the same manner.

My improved shuttle-motion is very simple in construction and reliablein its operation.

I claim as my invention l. The combination, with the shuttle providedwith a laterally-movable locking-lever, of carriers provided withlaterallymovable catches adapted to engage with said lockinglever, andstops and springs arranged on said 3. The combination, with the shuttlepro-' vided with an obliquely-faced locking-lever, O, of carriersprovided with pivoted catches which are held obliquely and whereby thelocking-leveris shifted, and springs which permit the catches to yieldafter the locking-lever has been shifted, substantially as set forth.

Witness my hand this 30th day of October, 1886.
